Bovine viral diarrhea (BVD) is an endemic infection of cattle caused by an RNA virus of the genus pestivirus of the family Togaviridae. Infection is usually inapparent but can result in abortion or congenital anomalies, respiratory signs or a frequently fatal systemic disease (mucosal disease) characterized by diarrhea, necrosis, and erosions of the ...

The National Animal Disease Laboratory (NADL) vaccine strain of bovine viral diarrhea virus (BVDV) genes for gp48 and p80 were expressed in Escherichia coli. The BVDV-NADL gene for gp62 was integrated into a baculovirus genome for expression in Spodoptera frugiperda (Sf-9) insect ovarian cells. The antigenicity of baculovirus expressed BVDV protein was

Bovine viral diarrhea (BVD) is prevalent worldwide and causes high economic losses in cattle due to a variety of disease syndromes. BVD is caused by three bovine pestiviruses, bovine viral diarrhea virus 1 (BVDV-1), BVDV-2 and HoBi-like pestivirus (HoBiPeV) with considerable genetic and antigenic heterogeneity.

SUMMARY Nine steers persistently infected with noncytopathic bovine viral diarrhea (bvd) virus were allotted into 3 groups (3 cattle/group). Cattle in group A were vaccinated with a modified-live bvd virus vaccine of porcine cell origin, cattle in group B with a modified-live bvd virus vaccine of bovine cell origin, and cattle in group C with a killed ...

Characterization of bovine viral diarrhea virus proteins
Journal of Virology, 1984Virus-specific proteins were examined in cultured cells infected with bovine viral diarrhea virus. By using antisera obtained from virus-infected animals, three major virus-specific polypeptides with molecular weights of 115,000 (115K), 80K, and 55K were observed. Minor proteins of 45,000 and 38,000 daltons were also noted.

Effect of levamisole on induced bovine viral diarrhea
Journal of the American Veterinary Medical Association, 1983Summary The effect of levamisole in calves experimentally infected with bovine viral diarrhea virus was evaluated in a double-blind study. The infection was mild and there was no difference in severity of infection or speed of recovery between levamisole-treated and 0.9% NaCl solution-treated (control) calves.

Structural Proteins of Bovine Viral Diarrhea Virus
American Journal of Veterinary Research, 1975SUMMARY A procedure for the purification of radioactively labeled bovine viral diarrhea virus was critically evaluated. Purification of virus from artificial mixtures of unlabeled infected and labeled noninfected cells indicated that the extent of purification was approximately 100-fold with respect to host proteins.

Bovine Viral Diarrhea Infection in Pregnant Swine
American Journal of Veterinary Research, 1980SUMMARY Twenty pregnant gilts (5 groups of 4) were infected experimentally with 1 of 4 strains of bovine viral diarrhea virus (bvdv) administered intranasally-orally. Blood specimens were taken from the gilts on postinfection day (pid) 7 and cultured for virus.

Biosecurity and biocontainment of bovine viral diarrhea virus
Veterinary Clinics of North America: Food Animal Practice, 2004Infection of cattle with BVDV results in a variety of clinical illnesses costly to the cattle industry worldwide. The reservoir and primary source of transmission is cattle born PI with BVDV after transplacental infection in early gestation. It is a challenge to determine with certainty whether or not BVDV is circulating among a herd of cattle.
